Method for customizing a beverage's carbonation level

摘要

The present invention recognizes the need for an apparatus and method for creating carbonated beverages having a customizable carbonation level. The invention uses a CPU to control an inlet valve which connects a tank of pressurized carbon dioxide to a vessel containing the beverage to be carbonized. The tube connecting the tank of pressurized carbon dioxide to the vessel contains an orifice for reducing the carbon dioxide's flow rate, thereby increasing control over the amount of carbon dioxide introduced to the vessel. A motor agitates the vessel, causing the carbon dioxide to become absorbed in the beverage. During the pressurization process, the pressure inside the vessel is monitored by the CPU to determine whether more CO2 should be added to the vessel. An outlet valve causes excess pressure to drain from the vessel. An outlet orifice causes the pressure to release gradually, thus preventing the beverage from foaming.

主权项

1. A method for creating a customized carbonated beverage, comprising the steps of:
receiving a user-selected carbonation level; storing, via a processor, the user-selected carbonation level on a memory connected to the processor; controlling, via the processor, a carbonation process including:
controlling, via the processor, an inlet valve to open to allow pressurized carbon dioxide from a pressurized carbon dioxide supply to flow into a mixing vessel;controlling, via the processor, a motor to activate to agitate the mixing vessel for an agitation cycle;receiving pressure information from a transducer, the pressure information including a pressure level sensed in the mixing vessel by the transducer;monitoring the pressure level in the mixing vessel based on the received pressure information;controlling, via the processor, the inlet valve to close when the pressure information indicates a first predetermined pressure level is reached in the mixing vessel, wherein closing the inlet valve stops the pressurized carbon dioxide from flowing into the mixing vessel;controlling, via the processor, the inlet valve to open when the pressure information indicates a second, lower predetermined pressure level is reached in the mixing vessel, wherein opening the inlet value allows the pressurized carbon dioxide to flow into the mixing vessel;controlling, via the processor, a timer to measure a saturation time comprising a length of time between identifying the first predetermined pressure level in the mixing vessel and identifying the second predetermined pressure level in the mixing vessel based on the pressure information; andcontrolling the carbonation process to cease when the saturation time is greater than a predetermined saturation time, and controlling the carbonation process to repeat when the saturation time is less than the predetermined saturation time.
